Detailed digital soil maps are needed to manage plant nutrients and plan land use effectively. In a study in Sri Lanka, soil properties in an Alfisol catena were examined to see how they vary in different land uses. Samples were taken and analyzed for pH, EC, organic carbon, CEC, and texture. The study found that pH and EC were strongly correlated, while other properties showed weaker correlations. The variability in soil properties was structured, with EC being affected by land use. This information can help with soil mapping, managing soil properties, planning land use, and understanding human impacts on the soil.
